Premise:
- 64MB blocks are allowed
- 64MB blocks take over 10 minutes to verify
- Someone wants to destroy the network ( 100 million dollar investment )
- Other miners want to let him destroy the network
Conclusion:
BITCOIN IS DOOOM!
there's nothing stopping the other miners from orphenning the attackers blocks... if his block give them much inconvenience for whatever reason they will orphen them...
EDIT. my now removed statement was on the bases of a 1mb attack. now lets make it 64mb..
if it takes 10minutes to validate a malicious 1mb. then it takes 640 minutes to validate a 64mb.. and so malicious miner is 638 minutes behind the competitors before it even begins to hash a block, because neutral miners will ignore such stupid transactions just like they ignore 0 fee transactions and make a standard block using more rational size transactions
